Abstract
An automatic focusing apparatus includes a photographing unit for photographing a transmitted light generated by applying a light to an observation target from a light source and an index value operation unit for operating to obtain an index value indicating focus information for the observation target from the image data outputted from the photographing unit. The automatic focusing apparatus also includes a focus controller for controlling a focus of the photographing unit so as to obtain an optimal focus position for the observation target on the basis of the index value, and uses a threshold value obtained from a background color of the image data to discriminate between the observation target and dust, thereby enabling proper automatic focusing on the target to observed even from the image data having the observation target and dust mixed.
